Supermicro X14SBI-F

Supermicro X14SBI-F – Compact LGA-4710 Solution for Intel Xeon 6 with MRDIMM and MCIO Connectivity

The Supermicro X14SBI-F establishes a new standard for high-density server infrastructure. Designed around the Intel Xeon 6 architecture (formerly Sierra Forest and Granite Rapids), this motherboard utilizes a streamlined 12.3″ x 10.5″ footprint to deliver enterprise-grade performance in space-constrained environments. It is specifically engineered to support the latest LGA-4710 (Socket E2) processors, making it a strategic choice for cloud service providers and businesses deploying containerized microservices or edge computing nodes that require the next-generation bandwidth of PCIe 5.0 and DDR5.

Optimized for Heterogeneous Compute Workloads

Flexibility is at the core of the X14SBI-F design. It seamlessly accommodates the full range of Intel Xeon 6 processors, supporting both Efficiency-core (E-core) heavy models for maximum thread density and Performance-core (P-core) variants for raw speed. With a power delivery system robust enough to handle Thermal Design Power (TDP) envelopes of up to 350W, the platform ensures stable operation for high-core-count CPUs (up to 144 cores), providing the computational headroom needed for complex virtualization stacks.

Breaking Bandwidth Barriers with MRDIMM

To prevent memory bottlenecks in AI and data analytics applications, this board integrates eight DDR5 memory slots with advanced signal integrity features. It is one of the few platforms to natively support Multiplexed Rank DIMM (MRDIMM) technology, capable of reaching transfer rates up to 8000 MT/s. For traditional deployments, it also accepts standard ECC RDIMM/3DS RDIMM modules up to 2TB capacity at speeds of 6400 MT/s. This allows system integrators to tune the memory subsystem precisely for low latency or massive capacity.

Cabled PCIe 5.0 Architecture (MCIO)

The X14SBI-F moves away from legacy board layouts by emphasizing cabled connectivity for high-speed I/O. It features six onboard MCIO headers (PCIe 5.0 x8), allowing NVMe SSDs to be connected directly to the motherboard without the signal loss associated with traditional riser cards or traces. In addition to these headers, the board offers physical slots—three PCIe 5.0 x16 and three PCIe 5.0 x8—providing immense flexibility for installing accelerators, FPGAs, or next-gen networking interfaces.

Storage and Utility Connectivity

While focused on NVMe performance, the platform ensures backward compatibility for diverse storage needs. An ASMedia ASM1164 controller drives four SATA 6Gb/s ports via SlimSAS, ideal for localized backup or boot drives. Additionally, dual M.2 PCIe 5.0 x2 slots offer a dedicated space for hypervisors, keeping the main drive bays free for data. Network traffic is managed by two efficient Intel I210 Gigabit Ethernet ports, serving as reliable utility uplinks.

Server-Grade Reliability and Management

Remote fleet management is handled by the industry-standard ASPEED AST2600 BMC. This chip enables secure, out-of-band access via IPMI 2.0 and KVM-over-IP, allowing administrators to troubleshoot OS issues or update firmware remotely. Hardware security is fortified by an integrated TPM 2.0 module, ensuring a trusted boot process and compliance with stringent enterprise security protocols.
